Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644432, here are decompositions:

101 + 8644331 = 8644432
131 + 8644301 = 8644432
179 + 8644253 = 8644432
383 + 8644049 = 8644432
479 + 8643953 = 8644432
491 + 8643941 = 8644432
509 + 8643923 = 8644432
593 + 8643839 = 8644432

Showing the first eight; more decompositions exist.
